MAINTENANCE AND WARRANTY

TROUBLESHOOTING/WARRANTY

7. My unit loses power at high speeds.

Your Tracker unit has over-voltage protection that turns the unit off when input voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the power output of the engine’s alternator and can produce voltage in excess of 20 volts when running at high RPMs. The Tracker unit displays input voltage in the Diagnostic screen. Use this readout to determine if the voltage exceeds 20 VDC.

8. The screen begins to fade out. Images are not as sharp as normal.

Check the input voltage using Diagnostic. The Tracker unit will not operate on input voltages below 10 VDC.

9.The display shows many black dots at high speeds and high sensi- tivity settings.

You are seeing noise or interference caused by one of several sources. Noise can be caused by other electronic devices. Turn off any nearby elec- tronics and see if the problem goes away. Noise can also be caused by the engine. If engine noise is causing the interference, the problem will inten- sify at higher RPMs. Increase the engine speed with the boat stationary to isolate this cause. Propeller cavitation can appear as noise on-screen. If the transducer is mounted too close to the propeller, the turbulence generated can interfere with the sonar signal. Ensure that the transducer is mounted at least 15" (38cm) from the prop.
